Abstract: A system for hanging an object (e.g., picture frame) at a desired location on a wall without measurements includes planar marking strips, each with an elongate body attached to a proximal head. The marking strips are removably attached to a mounting surface of the object so that the proximal head protrudes from an edge of the object and the elongate body aligns with a mounting hook, recess or opening on the mounting surface of the object. Once the desired mounting location of the object on the wall surface is determined, the user presses the proximal head of the marking strip against the wall surface and withdraws the object relative to the marking strip, leaving the marking strips attached to the wall surface. The distal end of the elongate body indicates the location for insertion of a fastener to mount the object at the desired mounting location.
